Speculation & Analysis

The external footage has been identified as the sinking of the USS Arizona at Pearl Harbor. ~ Dav Flamerock

Due to the "message" of the video, this could mean that Jay is "sinking". He starts resembling Alex: he starts to film himself. -baseballfuries08

The source or identify of the audio has yet to be identified, but it is a song much like Regards. ~ Dav Flamerock

The song in the clip is potentially the theme of the US Naval forces from around World War II. This would keep with the theme of water and boats in this and a few other totheark videos. ~ KaviCordi

The boat connection with this and other videos could help lead to determining another clue towards the identity of totheark. The owner of totheark might have some sort of obsession with boats, or naval service.
